Passenger window goes down but won't go up
On a recent trip, the passenger window in my 2001 durango R/T would go down, but it wouldn't go back up.
I took the door panel apart, and unplugged the window motor from the harness. Then I jumped 12V into the window motor, and it goes up and down fine. This implies that the motor and the tracks are fine.
My conclusion is that there is something wrong with the switches or the control module for the window (if there is a control module). Since the windows goes down fine, the wiring is probably ok as well.
I tried beating on the doors around the switches, and turning on and off the window lock button. Both switches (driver and passenger) will make the passenger window go down, but neither will make it go up.
I noticed that there are 5 terminals on the passenger side window up/down switch. I was unable to come up with a reason for there to be 5 terminals after thinking about it for a while.
1) Does anyone reading this know how this window circuit works? Is there a control module (with an H-Bridge), or is everything just handled in the switches?
2) If everything is handled by the switches, how can I test the switches?
2) Any theories as to what is wrong?
